Abstract

L'invention concerne un actionneur électromagnétique de soupape comprenant un organe d'actionnement (11,14) mobile sous l'effet d'un organe élastique (12,13) et d'au moins une bobine (20), et au moins un aimant permanent (22) agencé de façon à retenir l'organe d'actionnement (11,14) dans au moins l'une des positions extrêmes à l'encontre de l'organe élastique (12,13) lorsque la bobine (20) n'est pas alimentée, la bobine (20) étant associée à un noyau (16) comportant deux parties (17) ayant des premières portions de surface (21) en contact avec l'aimant permanent (22) et des deuxièmes portions de surfaces (23) qui présentent entre elles un entrefer (e) ayant une dimension très inférieure à une épaisseur (H) de l'aimant permanent. Selon l'invention, l'entrefer (e) forme un angle avec une direction d'aimantation (25) de l'aimant permanent (22).
